Migrate X.org repositories to GitLab

This is all tentative, and will be amended as feedback comes in. Apologies for any poor formatting, the markdown preview engine does not make this easy. Major highlights:

Things to delete:

• glvnd - vestigial, and subset of the upstream on github
• nouveau/mesa - ten years old and only one wip branch, probably can go away
• xorg/xserver-test - no idea what this was for

Things to divest to other projects / groups:

• xorg/app/intel-gen4asm - Mesa?
• xorg/app/intel-gpu-tools - Mesa?
